On September 25, 2014, the first MaxxForce engine of Anhui Jianghuai Navistar Diesel Engine Co., Ltd. was put on the line. On November 20, 2014, the Jianghuai Shuailing light truck with MaxxForce 3.2L engine was installed. Released. With the increasing sales of Maisford in the Chinese market, Maisford quickly attracted a large number of fans. Xiao Bian is also honored to be one of them. Today, Xiao Bian has come to give them some benefits. A look at the five advanced technologies of Maisford 3.2L.

New Concept 3.2L Gold Light Truck Displacement

Sometimes a correct direction is more practical than any high-end technology. Navistar smartly sees that the current high-end light truck power market in China concentrates on two displacements of 2.8L and 3.8L. Compared with the 3-5 tons of conventional cargo volume, 2.8L has a lower power performance, 3 -5 tons of load exceeds its optimal transport tonnage, fuel consumption level is satisfactory, 3.8L displacement power is abundant, but fuel economy is the soft underbelly of 3.8L. The displacement of the Mysford 3.2L engine is between 2.8L and 3.8L, and it is the gold displacement of the light truck, easily solving the balance of power and fuel economy.

Ultra-low friction, more accurate valve opening and closing

When it comes to the engine technology of Navistar, it is essential to his unique ultra-low friction valve system. Why should we reduce the friction of the valve?

Because the valve is the door to the switch into the exhaust system, it is an important part of ensuring the timing of intake and exhaust. Ultra-low coefficient of friction valve system valve friction coefficient is very low, the valve running more smoothly, opening and closing timing master more accurate, but also can reduce the valve during operation due to friction energy loss and parts wear, to reduce fuel consumption and extend The service life has played a role.

Good oil and gas coordination, grading to burn

What is the most direct way to save fuel? Yes, that is, every drop of fuel injected into the engine is fully burned. Maisford 3.2L adopts dual-axis variable turbocharging technology, which can improve the transient response of the engine in the full range of operating conditions, improve the power, economy and emission performance of the engine, and at the same time greatly improve the reliability of the engine. The latest light diesel engine today.

Cross-inlet and staged combustion technologies can perform staged combustion in different stages with different intake pressures, and fuel combustion is more complete. By cooperating with 1800bar high pressure common rail direct injection system, the engine can provide 310 Nm high torque at 1000 rpm. Whether it is power, fuel economy or reliability, it is more outstanding than the domestic same model. Bring a powerful dynamic experience and fuel-saving experience.

Lightweight design reduces body burden

In order to improve the transportation efficiency, the truck market is now popular with a thin wind, and the engine of the heart of the truck is to keep up with the downsizing. Maisford 3.2L uses a lightweight design of the cylinder block, cylinder head, the whole weight of only 315kg, more than 30% lighter than similar products. In particular, light trucks are not very heavy, so the weight can be increased by reducing their own weight, which can effectively improve the transport efficiency and reduce the fuel consumption of the vehicle.

Electronically controlled EGR balances fuel consumption and emissions

With the continuous improvement of national emission standards, automobile manufacturers are paying more and more attention to the emission control technology. Maisford 3.2L adopts the electronically controlled EGR system. This system can accurately control the position of the EGR valve through the engine computer and can not only meet the requirements of the National IV. Emission standards, and can be upgraded to European V, European VI emission levels, electronically controlled EGR can also achieve a balance of fuel consumption and emissions, reduce the energy loss caused by EGR.

It is not accidental that Mai Sifu can rapidly develop in China. It is these advanced technologies that support and promote it behind the scenes. I think the fans are also attracted by these advanced technologies. With the rapid development of science and technology, the engine has entered the era of science and technology. It is believed that Jianghuai Navistar will keep pace with the development of science and technology, and the engine world will bring more high-tech products. The fans will enjoy it. look forward!
